What check-digit algorithm does this use?

It uses the official Saudi Luhn-style algorithm — doubling the digits in odd positions (reducing two-digit results), summing with the even-position digits, then taking (10 minus the sum mod 10) mod 10 as the expected last digit.

How accurate is the result?

A passing check digit confirms the number is mathematically well-formed and starts with 1 or 2, but it cannot confirm the number is registered or active in Absher or any government system.

Is my ID number sent anywhere?

No. The validator is privacy-first — all processing happens locally in your browser and the number never leaves your device.

Saudi Iqama & National ID Validator

Saudi Iqama & National ID validator

Validate a 10-digit Saudi national ID or Iqama (رقم الإقامة) number. The tool reads the leading digit — 1 for a Saudi citizen ID, 2 for a resident Iqama — and verifies the number with the official Saudi check-digit algorithm, a Luhn variant used by the Ministry of Interior and Absher.

It is privacy-first: nothing leaves your browser. A passing check digit only means the number is well-formed — it does not prove the number is issued or active in any government system.
